AI Technical Summary

Technical Problem

In the nickel-cobalt hydrometallurgical production process, static electricity is generated by friction during the extraction process, which poses a safety hazard. Existing equipment has failed to effectively eliminate static electricity, resulting in a fire risk.

Method used

By incorporating a combination of speed reducers, flow guides, antistatic films, and conductive materials in the transmission device, and using a motor-driven transmission device, the flow rate of the solution is slowed down by driving the transmission wheel and transmission belt. An antistatic film is placed on the surface of the transmission belt to eliminate static electricity, while static electricity is also eliminated by guiding the solution to the ground through wires and controlling humidity.

Benefits of technology

It effectively slows down the solution flow rate, eliminates triboelectric charging, reduces the risk of static electricity accumulation, and ensures the safe and stable operation of the extraction production line.
